I wouldn't get your hopes up for anything impressive. They're still over a year late on the promised major interface changes that I believe were promised to happen in December 2016 / January 2017!
I'll be impressed when they add the option for multiple stops, give you multiple route options, and generally at least come close to the level of Google, Waze, or Apple maps.
When they switched over to AP 2.0 and realized how much trouble they were going to have making it equivalent to 1.0 (which they still haven't done), they basically forgot about every else they'd promised. And now with Model 3, they've gotten even further behind. Personally, I think that the Model 3 should have come out about another year later, when they had time to get everything right on S/X first, figure out the production line, figure out their quality control issues, and actually deliver the 3 as a finished product.
